PENCIL.

Application led February 28, 1921. Serial No. 448,318.

To all 'whom t may concern.'

Be it known that I, JAMES H. VVARING, a citizen of the United States,and resident of Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented certain new and'useful Improvements in Pencils;and I do hereby declare that the followin is a full, clear, and exactdescription t ereof.

My invention relates to improvements in pencils, and more particularlyto that type adapted to be refilled.

The invention has for its object to provide a pencil of this type whichis durable, eiiicient and positive in operation.

A. more specific object resides in the arrangement of lead feeding andholding means, whereby the lead is firmly engaged and projected from thepencil and positively held in its projected position to the extent thatretraction of the lead is impossible, without damage thereto. 4

Another object lies in the prpvision of encased operating means wherebythe lead is prevented from being accidentally projected from the pencil.

A still further object is to provide a pencil of this type. with ballfriction clutches for engaging the lead whereby a positive grip can beobtained and at the same time prevent damage to the lead.

With these and other objects in view which will be apparent as thedescription proceeds, my -invention consists in what is hereinafter moreparticularly defined and pointed out in the appended claims.

In the drawings:

Figure 1 is an elevational view of the invention, with parts broken awayand in section to more clearly illustrate the novel points ofconstruction, and

Figure 2 is a transverse sectional view through the lead projectingclutch, taken on 'the line 2-2 of Figure l.

Referring now more particularly to the accompanylng drawing, the numeral1 designates an outer casing provided with a tapered end 2 having fittedtherein byA any suitable method, a leadguide 3, provided with a centralrecess to permit the lead L to pass therethrough. Disposed within thecasm 1 adjacent its tapered end 2 is a clutcg housing 4f, providedqwith.inwardly MILWAUKEE, WISCONSIN, ASSIGNOR 0F ONE-HALF T0 PAUL F. SCHRYER,OF WAUWATOSA, WISCONSIN.

HEISSUED turned flanges 5 adapted to retain a pair of ball clutches Cand C which respectively project and hold the lead against retraction.

The clutch C comprises an .annular ring 6 slidable within the housing 4and provided with a tapered ball engaging surface, and a central opening7 which permits the ring to be mounted upon the end of a leady housing8. Surrounding the lead and disposed within the annular` ring 6, are aplurality ofv ripping balls B, which are retained in t ieir place by aball retainer 9.'

The clutch C which opposes the clutch C to prevent retraction of thelead, is similarly constructed and disposed between its annular ring andthe ball retainer 9 of clutch C, is a spring 10 adapted to render bothclutches operative, and having an additional function. of returning theclutch C to its normal position after the lead has ,been projected. rlheball retainer 9 of the clutch C is provided with a recess 9 to receivethe lead guide 3.

The open end of the casing l is provided with a collar 11, having acentral orice to permit the lead housing 8 to extend therethrough.Fitted over the end of the casing and abutting the annular flange 1 is asleeve 12 provided with an enlarged end 13, which lend is turnedinwardly to provide a retaining bead 14. Confined within the enlargedend 13 is a cap 15 adapted to engage and operate the lead housing 8, thecap having its movement limited in one direction by the bead 14 and inthe opposite direction by the' shoulder 16 formed between the sleeve andthe enlarged end 13.

From the foregoing it will be seen that as the cap is depressed, theclutch C mounted on the end of the housing 8, will grap and projectthelead from the guide 3. Upon releasin the cap the spring 10 will causethe clutch to be returned to its normal position, and at the same timewill render the clutch C operative upon any tendency of the lead to beretracted by the clutch C upon its return movement. It will further benoted that when the clutch C is in its normal position, the clutch Cwill cooperate with it to assist in preventing the lead from bein pushedback when pencil is in use.

Wile I have shown and described one specific method of carrying out mypresent "ies invention it will he understood that various changes inminor details of construction are masones surfaces, a group of balls, aballretainer, a second ring, a second group of balls, said ring havingball engaging surfaces, a sprinor contacting with said second ring andsai retainer, a second ball retainer, a lead guide rigid therewith, ahousing for said spring, said rings, said balls, and said retainerslimiting the movemento said irst mentioned ring, and a casing envelopingsaid lead housing, said second mentioned housing and said lead guide.

- In testimony that claim the foregoing have hereunto set my hand atMilwaukee, in the county of Milwaukee and State of lWisconsin. JAMES H.WARING.
